Czech the spark plugs to see if they show the presence of oil in the combustion camera, if it is not ahy, check the air recirculation of the carts that goes to the hose of the air filter and check that is not there, if the water is not check the water Porsi if it is happening for there, there is no shape that disappears Czech well before to help you.

If your engine works well and does not throw blue smoke and consume oil, the most common is that your valve stamps occupy replacement.

But however you can use motor reclamar products such as restore or lubrifilm that will help you lower your oil consumption.
These products do not increase viscosity, what they do is provide a metal protection layer in engine wear areas.

He also remembers that there is an integrated metallic filter to it in the edge lid. You have to clean it perfectly and check the breathing flow control valve.
